Notoedres are burrowing mites of cats, rats, man and rabbits. They are also common ectoparasites of tropical bats.
Identification
The Notoedres mite is similar to Sarcoptes although it has less distinct angles on its body surface. The female mites have suckers on legs 1 and 2 and are about 225μm in length. Males are 150μm in length. The anal opening of the Notoedres is distinctly dorsal, not posterior.
Diagnosis
The method of detection for Notoedres is usually via a superficial skin scraping. A single nest in a scraping may yield many mites.
